12.4. Coupling

There is no resistance when pressing a pedal of coupling:

– the mechanism of adjustment of a cable of coupling (coupling with the hummock drive) is faulty;
– the hydraulic system of switching off of coupling (coupling with the hydraulic drive) is faulty;
– the bearing or a fork of switching off of coupling is broken;
– the diaphragm spring in a press clutch plate is broken.

Coupling is constantly included:

– the coupling adjustment mechanism (coupling with the hummock drive) is faulty;
– the hydraulic system of the drive of coupling is faulty;
– the clutch plate on vents of an entrance shaft of the transmission is jammed;
– continuous contact of a clutch plate with a flywheel or press disk;
– wrong assembly of a press disk;
– the coupling switching off mechanism is worn-out.

Coupling pro-slipping:

– the mechanism of adjustment of a cable of coupling (coupling with the hummock drive) is faulty;
– the hydraulic system of the drive of coupling is faulty;
– excessive wear of overlays of a clutch plate;
– overlays of a clutch plate are polluted by oil or lubricant;
– the disk or a weak diaphragm spring is faulty press.

Intensive vibration at coupling inclusion:

– overlays of a clutch plate are polluted by oil or lubricant;
– excessive wear of overlays of a clutch plate;
– the disk or a diaphragm spring is deformed press;
– wear of support of the engine or transmission;
– wear of shlits of an entrance shaft of the transmission or nave of a clutch plate.

Noise during the pressing or an otpuskaniye of a pedal of coupling:

– the release bearing is worn-out;
– coupling pedal plugs are worn-out;
– the disk is incorrectly built press;
– the diaphragm spring of a press disk is broken;
– the clutch plate damper spring is broken.
